Vinyloxy monomers, copolymerization

Modes of Copolymerization of Vinyloxy Monomers with Electron-... 

We have explored in some detail the structure-reactivity relationships for vinyl- and allyl-ethers derived from polyhydroxylic compounds (mainly isopropylideneglycerol or ribose derivatives) for the free radical donor-acceptor copolymerization with diethyl fumarate (DEF) and diethyl maleate (DEM). Other allylojy and vinyloxy monomers with a more simple structure were also used as model compounds. The synthesis of non commercial but known monomers (ACG, AHE, AIG, HVE, VCG, VIG), as well as of the original pentose-based monomers (AIR, AR, ATMR, VIR, VTMR) was achieved by conventional laboratory methods, using appropriate catalysts and trying to minimize the use of solvents for chemical modification and for separation.
